a,b, Iron (a) and zinc (b) concentrations in storage roots of VIT1 transgenic cassava plants. c,d, Iron (c) and zinc (d) concentrations instorage roots of IRT1 + FER1 transgenic cassava plants. For VIT1, n = 9 biologically independent plants (3 plants/replicate); for IRT1 + FER1, n = 4 biologically independent plants. Box-and-whisker plots were constructed with the R package ggplot2. The upper whisker extends from the hinge to the largest value, no further than 1.5× the IQR from the hinge. The lower whisker extends from the hinge to the smallest value, at most 1.5× the IQR of the hinge. Data beyond the ends of the whiskers are considered outlying points and are plotted individually. Statistical tests were performed with two-sided Student’s t test, relative to nontransgenic control. *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001.
